Three Waters

Our Three Waters services sector includes local and regional councils.

Key challenges facing this sector include ageing infrastructure, historical under-investment, a number of wastewater plants to be reconsented, source water contamination, higher public expectations and resilience needed for impacts of climate change.

Our technical capabilities support cost-effective water supply, wastewater discharge and stormwater management and treatment solutions, including source selection, compliance monitoring, concept/detailed design and commissioning. Our team also offers sewerage infrastructure development, trade waste management, and supporting services such as planning, environmental impact assessments and consent submissions.
